How to remove all file relating to uses

I have removed accidentally the user's home directory like /home/rabbani ,
home/guest and after removing the directories my redhat enterprise Linux not
log in with the uses rabbani and guest. after that I deleted the uses and
created again but still too many errors show while I log in with the
specified users.

Now I like to delete the all user's specific file like setting/configuration
etc. How can I do this ?

Hope I understood the context correctly. You have
deleted some user's home folder and then the user
can't login. Then you again create the same user (i.e.
same user name) and try to login but still get lot of
errors. Delete the user entry from the /etc/passwd (If
you don't want that user ) create a new user(if you
want repeat the same user name as previously) like
"rabbani", specify the home directory options and all.
Hope this will work.
